SEND_MAIL functionality fails if the Automation Engine (AE) has a higher build version than the Agent and the above error message is displayed.
The sending of emails depends on the user's PC configurations. The parameters Agent and Login may also be defined client-wide in the UC_CLIENT_SETTINGS variable, using the key SEND_MAIL_DEFAULT. Settings in individual SEND_MAIL script functions will be overridden by the key in UC_CLIENT_SETTINGS anywhere throughout the respective client.
Cause type: By design Root Cause: Use v10 agent with v12 Automation Engine to SEND_MAIL
OS Version: N/A
Upgrade the version 10 Agent to version 12 for the SEND_MAIL functionality to execute.
Fix Status: No Fix
Fix Version(s): N/A
Workaround : Our recommendation is that you use one of the following options:
Use a version 12 Agent for SEND_MAIL (upgrade the Agent)
Send the Mail via the Server with "SERVER" instead of the Agent (If you don't specify an Agent, the email is set by the AE Server).
